Building BIOS Architecture

Events shall be classified by function, severity, origin, confidence, and required response.

Functional event classes shall include:

identity events;

discovery events;

registration events;

configuration events;

connection events;

state-transition events;

operational events;

resource events;

diagnostic events;

fault events;

alarm events;

safety events;

security events;

maintenance events;

inspection events;

update events;

override events;

recovery events;

lifecycle events.

Severity levels shall include:

Informational: records a normal occurrence requiring no action;

Advisory: identifies a condition worth review;

Warning: indicates developing degradation or reduced margin;

Action Required: requires planned intervention;

Critical: requires immediate protective or operational action;

Emergency: indicates imminent or active danger requiring emergency response.

Event confidence shall indicate whether the event is:

directly measured;

physically verified;

device-reported;

manually reported;

inferred;

predicted;

unverified.

Origin shall identify whether the event was created by:

BIOS Core;

registered component;

Cartridge;

sensor;

controller;

human user;

robot;

AI service;

external authority;

imported record.

Severity shall not be determined solely by the producing device. BIOS policy may raise or lower operational response based upon context, dependencies, redundancy, occupancy, and Engineering Profiles while preserving the original reported severity.
